In Fig. 1 the mechanical peg 1 is shown up and in contact with the ramp (S suspended from the trani-car and about to be depressed by the sloping tread-piece G' of the ramp, and the drag-rod 1T is shown engaged with the catch-pin 20. As the tram-car pushes down the`peg the cam 102 will rise and simultaneously push back the rocking lever 18, thereby pulling up the contact-peg 15)"and mechanical peg l in the box next forward by means of the connections hereinbefore described, and this operation is assisted by the action oi' the runner-wheel l.) operating on the eamhead, as hereinbefore mentioned.

The lower end of the link 4C is connected with the cross-shaped lever l0 by a pivot-pin 10 and its upper end may be attached by a split pin 5, Fig. 3, to the cross-head 3 that connectsthe mechanical peg 1 and contactpeg 19, the relative arrangement of which is shown in Figs. 3 and el. The contact-peg 15)' has a depending rod 192, carrying on its lower end a bow-spring 21 sliding in a socket 22 at the bottom of the box A and thereby making electrical connection with the conductor or cable 2l through an intermediate connection between the said socket and cable. The contact-peg 19 is provided with insulation at 193 and 1514, as shown in Fig. l.

After the contact-brush 25, carried by the car, has made connection with and passed over the elevated contact-pcg 19' of one of the boxes A, the ramp G on the car will pass onto and depress the mechanical peg 1 of that box, thereby lowering, also, the connected contactpeg 19/ and actuating the link l and connected lever mechanism, hereinbefore described, in such manner as to lift the pegs 1 and 19' in the next forward box, and so on, thus furnishing a continuous supply of electricity to the car-motor.

In the foregoing speciiication I have described my apparatus as employing a contact-peg separate from the mechanical peg; but one peg may be used for the double purpose.

To bring the automatic apparatus into action, it is necessary when a car is first started from the station or terminus to raise the iirst peg into contact by some suitable additional appliance or by hand. The same may also be necessar f in case of accident to any peg in the course of a journey or where it is desired to back the car. There are many ways of doing this. The action required is first to raise a peg outside the length of the car and again depress it so as to raise the one under the car. At the station it may be done by means of a mechanical pcg being prolonged to a suitable heightabove the floor-level and provided with a cross-head or other handle for the convenience of the operator in iirst pulling and then pushing. On a journey a ditferent method must necessarily be used, but the nature ol' the opera-tion is the same. I make no claim to any particular method, and I do not confine myself to any particular method ol eIlecting the operation. I the place o1 operation be at some distance Afrom a car, so that the lirst peg raised is outside the length o'l' the car, then the peg so raised or any number of pegs eollsecutivcly raised may be pushed down by the foot until finally a pcg is raised under the car.

'lo meet the case of a car getting oil the track, the cars will carry a suitable length ol' spare cable aapable of attachment to any contact-peg and so establish connection between the car and the cable below the roadway.

In an application, Serial No. 502,015, iiled by me March l 1S94, I have shown, described, and claimed the combination, with a series ot' vertically-1novable contact-pegs adapted to complete the circuit bcween a car-motor and an electric supply-cable, and peg-actuating mechanism arranged in a series of boxes to gether with said contact-pegs, of mechanical and positive means for elevating a peg in one box by the depression ot a peg in the box next behind through suitable connections from box to box, and I have also therein claimed the combination, with an undergrouml electric conductor, el' verticaliy-movable contact-pegs adapted to complete the circuit between the said conductor and the car, a ramp carried beneath the car, and mechanism operated by said ramp for raisin g and depressing said pegs to make and break the circuit. In the said application the contact-pegs and mechanical pegs are shown as directly mounted upon and carried by rocking levers arranged in pairs and connected by rods with similar levers in adjacent boxes, and to provide tor runninga car both ways on the same line oi' track each contact-peg is accompanied by two mechanical pegs, and two ramps are provided on the car, one for each direction in which the car is to run. The construction, arrangement, and combination of devices shown in the aforesaid former application I do not herein claim; but

lVhat I claim as my invention is- 1. In apparatus for operating electric railways from an underground electric supplycable, the combination of a series of vertically-movable contact-pegs adapted to complete the circuit between the car-motor and said electric supply-cable, a series of vertically-movable mechanical pegs each provided with a stud or cross-arm that carries one of the contact-pegs, a series of boxes arranged at intervals for containing said pegs, lever mechanism located in each of said boxes, a link having its lower end connected to said lever mechanism and its upper end connected to the stud or cross-arm that connects a mechanical peg and a contact-peg, connections from the lever mechanism in each box to the similar lever mechanisms in adjacent boxes,

and a ramp, carried beneath a car to engage a raised mechanical peg and canse the depression of the pegs in one box to elevate the pegs in the next forward box, substantially as described.

2. In apparatus for operating electric railways from an underground electric supplycable, the combination of a series of vertically-movable contactpegs and connected vertically-movable mechanical pegs, series lof boxes arranged at intervals for containing said pegs, a cross-shaped lever 10 pivotally supported in each box and carrying a cam 102 on one end, the lever 1S provided with arm 183 and carrying a runner-wheel 19 and catchpin 20, the link 4L connecting each pair of contact-pegs and mechanical pegs 'with one arm of the lever 10, a two-armed lever 9 in each box, `a drag-rod 17 pivoted to one arm of the lever 9 and having a notch adapted to engage the catch-pin 2O of the lever 1S, rods 15 and 16 connecting the two arms of lever 9 with upper and lower arms of a lever 10 in the next forward box, a spring 14 connected with arm 1S3 of lever 1S, and a ramp 6 carried by a car and adapted to engage and depress a raised mechanical peg, substantially as described.
